2TZ-FE engine

[SigmaProjects]

Does anyone know about this engine. All I know is that it's a 2.4L 4cycl and there's a 2TZ-FZE supercharged version. These two engines go into a previa so at least the N/A version is pretty easy to get. What I'm curious about is if it's an aluminum or an iron block and how much larger of an engine is it? I'm planning on using this to swap out my old 22RE out of my celica, I'm not really looking for serious power ( but there is always the option for the 2TZ-FZE supercharged engine), I'm mainly looking in to it as a reliable replacement. These engines should be durable since the previas are 37XXlbs vans. Before you guys start saying "go with a 3S, 1JZs, 2JZs, 7Ms, etc.," I've checked them out and right now the 2TZ-FE is the cheapest and seems pretty close to the original setup. I thank any info in advance.

don't know much about a 2TZ, but the Previa did not hav the best reliability record in the US. I've seen a lot of them with bad cats.

I wouldn't be concerned about the cats, but what was the main problem with the engine, since I'm concerned with the power train, mainly the engine and tranny. I also thought it might be nice since the 2TZs had to endure the stress of 3700+lbs while in a 84 celica it would only have to push 2430lbs that's a little over half a ton, big difference. If you have any links to it's reliablity issues or defects the previa had I would greatly appretiate it Thanks for your info.

I never got specifics for it, and I don't think the engine was part of it, mainly crash protection, transmission weardown, stuff like that. NTSB.gov or NHTSA.gov should have info about recalls on that model previa. Hope you don't live in Cali, b/c you'll never get that swap to pass referee (car to car, truck to truck, no mixing, and Cali looks at minivans as trucks)

Yea I live in cali, I'm hoping to go through a friend of my dad's, hopefully we can just get it tested for emessions. Thanks again for your response.
